All those nodes with no device name listed need to be removed.... holy cow.
Not sure how they all have routes and multiple Neighbors. You might need to run a full repair so all the other nodes will see those are dead and remove the neighbor entries.
Did you just force delete devices from the device list, or having problem pairing devices and a lot of failures?
See this guide, it has instructions for how to remove WITHOUT a separate USB stick, try that first.
